LOUIS SLOBIIT, OF NEWARK, AND I'IYMAN KAUFMAN, 015 ROSELLE, JERSEY.

Application filed August 18, 1919.

To (/ZZ whom it mm," concern liie it known that we, Louis SLoBIN, a citizen of the United States, residing at Newark county of Essex, State of New Jersey, and HYMAN TZAUFMAN, a citizen of the United States, residing at Roselle, in the county of Union and State of New Jersey, have invented a new and useful Metal-Bed (Turner-Stock, ofwhich the following isa specification.

This invention relates to metal beds, and particularly to a fastening for bedstead corner posts and rails. beds are constructed from tubes and angle bars joined by corner stocks consisting of dovetailed wedges or keys and dovetailed kcyways or sockets, the former being cast onto the angle bar and the latter being cast onto the tubes which form the corner posts of the beds. This cornnion inethodof making inetal beds requires large, expensive molding equipment, and therefore places this branch of the bed industry beyond the reach of smaller individual manufacturers.

T he purpose of this invention is to make it possible for an individual or small inanufacturer to assemble the various parts of the bed and be independent of a foundry. Another object is to make such assembling easy and rapid. A f'Lllftl'lGl object is to do away with casting, welding, bolting, riveting and like methods of joining posts and rails. Other objects are to provide a strong, secure, dependable corner stock which will facilitate the manufacture and assembling of metal bed parts.

These and other objects are carried out in the construction described below, reference being made to the accompanying drawing forming a part of this spectification, with the understanding that various changes in the form, proportion, size and details, may be made without departing from the principle of this invention, provided that such changes and modifications come within the scope of the appended claims.

In said drawings:

Figure 1 is a perspective view of the invention in place on the corner posts of a bed;

Fig. 2 is a horizontal, sectional view through the corner stock and a post showing the relative positions of each;

Fig. 3 is a perspective view of a portion i of the post showing the slot;

Specification of Letters Patent.

Ordinarily inetal Serial No. 318,351.

Fig. 4- is a perspective view of the key piece which is a part of the corner stock;

Fig. 5 is a like view of the socket block whichforlns the coinpleinental part of the corner stock and Fig. 6 is an end elevation of the same part. Referring in detail to the drawing, it is seen that the reference numeral 10 denotes the corner post of a metal bed. At a convenient location each post has a slot 11 formed therein of an elongated keystone shape, with the sides 12 tapering to an incr asing width toward the lower end where is located the notch or seat 1d and the shoulders 13. The slot 11 is formed to receive and hold a key piece 15 of the corner stock located within the post. i

The key-piece 15 is preferably of cast metal and consists of a base or web larger than the slot 11 and rounded on one face to "fit snugly against the inner wall of the corner post about the slot. Outstanding from this rounded face is an elongated tapering key 16. The taper of this key is like that of the slot 11 through which it is designed to pass. The length and width of the key is such that it can just pass in or out ofthe slot between the shoulders 13 and the upper end of the slot. The key substantially oval in cross section, with a narrow neck 1'? joining it to the base or web and it occupies a position on the base removed from the ends and sides thereof. The taper of this neck must be such as to cause the lower end 18 to fit snugly within the notch or seat 1% of the slot and thus rcniovably hold the post and key-niece together. The neck widens where it joins with the base of the l zey-piece into a keystone-shaped shoulder 17. which is designed to close the slot 11 and provide a solid lit.

The socket block 19 is also formed from cast metal and has two vertical sockets or key-ways one at each end. Key-way 21. which is open at both ends, runs from top to bottom of the socket block, and is tapered as Fig. 6 shows to receive the keyed ends 26 of the side rails 25. The face 20 of the end out of which the key-way 21 is formed, is flat. The opposite endhas a curved face 22 to cause the socket block to fit snugly against the outer surface of the corner post as Fig. 2 illustrates. The curved face 22 is broken by a key-way 23 which is tapered from the Patented Mar. 22, 1921.

bottom to the top since it is designed to receive the key 16 of the key-piece. The key-way 23 terminates short of the top of the socket block and ends with shoulder 24 designed to rest upon the upper end of key 16 when the parts are joined.

The taper of the inner keyway is toward the top, while the taper of the other keyway is toward the bottom.

In assembling the bed, the corner posts having been formed and slotted as described, the key pieces are first slipped through the slots. Then the socket blocks are fitted to the keys of the key pieces, a light tap with a hammer sufficing to interlock the parts. Then the side or end rails are secured by their keys to the outer ends of the socket blocks.

, A strong, durable bed corner fastening is provided by the above described construction, one which will make assembling easy and rapid, and one which allows an individual to do the assembling witnout resorti to casting, welding, bolting, riveting or the like. We do not wish to be limited to the particular use herein described for this invention, as other useswould suggest themselves to the skilled mechanic.

The post 10 may be made square, octagon or otherwise shaped to suit the fancy of the manufacturer, and in such event the base of the key-piece shown rounded in the drawing, as well as the curved face 22 of the socket block, would have to be altered in shape to correspond with the inte *ior or exterior shape of the post.

Having described the invention what we claim is:

l. A hollow post having a longitudinal slot in the wall'thereof, a key-piece having its base portion held within the post and shaped to fit the same, and an elongated tapering key connected to the base piece by a neck, said base piece where it joins with the neck being provided with a longitudinal shoulder of a length and width to lit the slot of the post, and a socket block provided with a tapering keyway to receive the key of the keypiece.

2. A tubular post having a keystone shaped slot in the wall thereof, in combination with a keypiece consisting of a tapcrin key, a reduced neck, a base portion, and a keystone-shaped shoulder on the base portion where the neck joins therewith, said shoulder being of a length and width to lit and close the slot in the post, and a. socket block having a tapering keyway to receive the key of the keypiece.

3. In metal bed construction, a tubular post having an elongated keystone shaped slot in the wall thereof, said slot comprising sides tapering upwardly and a lower end having a notch or seat bounded by shoulders. a keypiece comprising a base portion of dimensions larger than said slot, a keg.' formed integrally with said base portion and joined therewith by a narrow neck, 'd neck widening where it joins with the base portion of the key-piece and formed into a keystone shaped shoulder, the key, the neck and the shoulder all tapering upwardly, the length of the key being less than that oi the slot whereby it may be moved into said slot between the shoulders'annil the upper end oi the slot and then moved dowmvardly. the keystone shaped shoulder fitting into the slot after said downward n'lovenient has taken place.

In testimony that we claim the foregoing as our own, we have hereunto allixed our sign natures in the presence of two witnesses.
